I don't believe the NetBIOS name is relevant here, but I'm sure someone will correct me if I'm wrong.

My understanding is that when your SMTP host (which is set to mail.owenwilliams.co.uk) communicates with the outside world, some hosts will try a reverse DNS lookup to prove that you are who you say you are. Your ISP needs to set your reverse DNS up so that anyone querying your IP address of 193.133.143.82 gets an answer of mail.owenwilliams.co.uk (I think).
